Meet the next generation thermostat. Most people leave the house at one temperature and forget to change it. So Nest learns your schedule, programs itself and can be controlled from your phone. Teach it well and Nest can lower your heating and cooling bills up to 20%. Only 11% of programmable thermostats are programmed to save energy, but Nest remembers the temperatures you like and builds a schedule for you. It's so simple that 99% of Nests have schedules.
